HERBERT sTE'ELINe WILSON,

OF ST. LOUIS, MISSOURI.

MACHINERY FOR PRODUCTION OF LIQUID AND MOISTURE PROOF PACKAGES.

To all whom it may concern:

Be it known that I, HERBERT 8 WILSON, a citizen of the United States,residing in the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Machinery for Productionof Liquid and Moisture Proof Packages, of which the following is aspecification.

This invention relates or pertains to that class of machines orappliances in which a roll of paper, cloth, or fibrous material-isconverted into shells or tubes adapted to form the outer walls or sidesof packages and a machine ordinarily consists of elements or partswhich, while performing difl'erent operations, co-act and are combinedinone machine which operates as a whole and is to all intents andpurposes a single machine.

The various elements or portions of the machine among others to beprovided for are; first, a friction device or retarder to prevent racingor too rapid unrolling of the paper roll or other material; second, oneor more printing devices in order that the paper may be printed in oneor several colors; third, means to cut or sever the paper or fabric intosuitable lengths; fourth, means to transfer the web or feed thesam'through the machine; fifth, means to permanently curl or bend theweb or strip of paper for a part or the whole of its length; slxt-h,means to apply a liquid or moisture proof adhesive to the paper;seventh, rolls or other suitable means to remove the surplus coating ofsuch material; eighth, a chuck or windingmandrel capable of contractingandexpanding".

whereby the finished or Wound shell may be loosened thereon; ninth,a'strippingringor ejector adapted to dischargethe. shells from themandrel; tenth, a receiver to catch the completed shell, and; connectingmechanism to operate the various cooperating elements of the machine.

'In order that a full and complete understanding of this inventionmay behad I have illustrated a-desirable embodiment of the same in theaccompanying drawings which form a part of this specification and.

throughout the various views of which like reference characters refer tothe same parts. i t

In these drawings;

Figurel is a diagrammatic elevation of a machine incorporating thefeatures of this invention; Figs. 2.and 3- illustrate on an enlarged'scale'the details of Specification of Letters Patent. Application filedOctober 11, 1909.

embodying this invention prising eleventh, a suitable passes, the samebeing held in I 4 tact .with such rollers by the additional PatentedAug. 19,1913. Serial No. 522,350.

construction of the curling device; Fig. 4 indicates the manner in whichthe paper is curled; Fig. 5 shows in section and fragmentary elevatlonthe features of construction of the grooved rollers and cooperatingbelts; 'Fig. 6 right angles to one another showing the roll of paper andthe retarding mechanism; Fig. 7 illustrates the features of the last orfinal set of printing rollers which also comb'ine the cutting orseparating knife; Fig. 8 is a longitudinal sectional view of the mandrelor winding head and indicates the manner of loosening the finished shelland the means to eject the same from the mandrel.

By referring to these drawings it will be noticed that the roll of paper1, of suitable and desirable width, is supported on a central arbor 2,the protruding ends of which are rotatably supported in bearings. ornotches 2 in the frame 2 brake, weight, or friction device 3 hingedtothe frame of the machine at 3, bearing on the top of the roll of paperand being designed to provide a continuous and uniform tension on thepaper web 51, such element 3 acting, as will be readily understood, to

prevent racing ortoo rapid 'unrolling of the -'--paper. A gage 52 ismounted, as shown. in

igs. 1 and 6,"on the bar or member 31, and is .designed to act as aguide to-hold the strip of,

of the machine, a

roll in the same, or proper position at each v renewal. I T-wo cylinderprinting presses are mounted on the machine frame, the former comrollersor devices 5, v6, and 7, which, .as will a an inkwell La nd inkdistributing be readily understood, are adapted to apply the-ink to theprinting cylinderS. The companion printing press has itscylinder 13supplied with ink. of the same 'orany other suitable color by means ofthe-ink well or container 10, and ing rollers 9, ll, and 12. Beneath thetwo printing rollers 8 and 13 I mount two companion rollers 14-and 16capable of vertical movement toward ers, and operated'bymeans of a cam21 on a shaft 21*, such cameo-acting with a pair of suitably fulcrumedbell-crank levers 18 and 19 cooperatingby means of proper connectingIneclianism'with the two rollers 14 and 16, over which the web and fromthe upper roll-v the co6perating' -distribut of paper -51 suitable con-'means of a chain belt 23 passing around a sprocket wheel or pulley 20 onthe shaft 21* and a similar sprocket wheel or pulley 418 on hereinabovethe main-drive shaft 18. The printing cylinder 13 is recessed asindicated in Fig. 7 to accommodate a knife blade 53, which is adapted topartially sever the web of paper into individual blanks, the blanksbeing attached to one another preferably by a small un-severed portionat the center ofthe cut.

The vertically-reclprocatory companion impression roller 16 is providedwith a relatively soft-block 53 with which the knife blade is adapted toco-act in its severing or cutting operation, brought into registerduring the rotation of the rollers as is clearly illustrated in Fig. 7.

Beyond roller 16 the machine is provided with a pair of rotatablymounted drums 17 and 24: encircling which is anendless traveling belt orconveyer 22 adapted to conduct the web of paper from the printingmechanism to the curling ortion of the structure. Above the rolleremploy a similar revoluble roller or drum 25, capable of verticalmovement toward and from the roller 24, and spring pressed downwardly,such roller beingali ted at intervals by any suitable form of mechanism,such for example as by a lever 42' fulcrumed at, 42*, such lever beingin cooperative relation at its upper end with the roller and its lowerend coacting or drums 24 and 25 a're'driven in any approved manner at aspeed such as to cause the paper between them to travel faster than itdoes through the printing mechanism described, 1 such acceleratedmovement of these; feed rollers acting to separate the partially severedblanks from the remainder of the web. 7

At one side of the feed rollers 24; and 25 an intermittently-operatedcurling mechanism is located, com rising a stationary bent bar or blade2'? astened or secured to the standard carrying the feed roller 25..

Below the depending-end ofsuch bar I provide an oscil atory curling baror blade. 27

having a relatively or =comparatively sharp edge adapted to he -"swunginto juxtaposition to the lower edge of the bar or blade 27", in whichposition'it is adapted to curl the stripfor band of paper drawn over thesame. In Fig. 2 this curling bar or blade is shown in inoperativeposition the web or strip of paper 51 passing above the same and belowthe bar 27, no curling of the same in these the knife and block being.

ble rollers 29, 31 57, 58, 31,

with an actuating cam- 54. Rollers no /ones positions of the partstaking place, but when the bar or blade 27 is swung into substantiallyvertical position as indicated in Fig. 3 the drawing of the paper acrosssuch top edge occasions or brings about a permanent curling of the same.In order to secure the proper timed oscillation of the bar or blade 27the same is equipped with a pinion or gear 27 c the teeth of which meshwith those of a substantiallyvertically disposed rack 27 connected atits lower end to a springdrawn lever ll fulcrumed at 43 and adapted tobe rocked by a suitable cam 54c on the main drive shaft 48 On the frameof the machine adjacent to the curling mechanism I employ a receptacleor pan 40 adapted to contain the coat.- ing liquid, which is preferablythough not necessarily a water or moisture-proof adhesive, such forexample as parafiin, which 'ater-proofs the strips of paper and actswhen set to cause the various convolutions of the paper shells or tubes.This receptacle may be heated in any approved manner to maintain theparafflu or other coating material in a liquidstate, the level of suchliquid being indicated by the dotted line? In order to feed or conveythe preliminarily-curled strips or sections of paper through the meltedparafiin bath contained in the receptacle 40 I provide the six rotata- Iand 30. A plurality 'of endless preferably elastic metallic conveyers 55pass around the rollers 58, 31, and 30 and co-act with the roller 31.Similar bands or conveyers 56 pass around the rollers 29, 57, and 31?,traveling in grooves 31 in the latter roller so that as the strip ofpaper passes beneath the roller. 31 between the conveyer bands 55 and 56it will not be injured or crumpled. The rollers-29 and 80 are alsopreferably grooved to hold the conveyers 55 and 56 in proper spacedrelation, the other rollers 57 and 58 being similarly grooved if foundto be desirable or necessary.

A, hollow rotatable mandrel 35 is mounted on the top portion of one endof the machine-and is provided on its cylindrical periphery with aplurality, (in the present instance four) of longitudinal taperedundercut grooves accommodating a corresponding number of reciprocatorydovetailed wedge'or tapered bars 36? connected together by a commonmember 36 on the end of a slidable hollow rod or shaft 36" perforated/orapertured inside of the mandrel orform to permit, if necessary, theheating of the mandrel from its interior by means of steam or otherheating element fed to the rod 36 and escaping through its aperturesagainst the inner'surface of the form. Slidable lengthwise thereon themandrel has a round stripper or ejector 38, revoluble with the mandreland contained within a non-rotary ring or support 38- attached to anoperating rod 39 adapted to be shifted .at proper intervals by means ofan appropriate mechanism, such for example as a cam actuated device.Partially surrounding the mandrel or winding head 35 is a curved guideor shoe 37 carried on the upstanding end of an arm 37 fulcrumedrat 37and equipped with a finger 37 co-acting with a similar finger 32 on aframe 32 fulcrumed or hinged co-axially with the roller 58, said frameat one end carrying a pair. of rotatable rollers 33 and 34 between whichand the mandrel the strip of paper is adapted to pass to the curvedguide or shoe 37. The revoluble roller 57 is also mounted in the frame32 and the latter is rocked at intervals by means of a link 32 pivotedthereto and also pivoted to the end of a lever 32, which is rocked bymeans of a cam 44.

50 represents a fixed guide, which also assists in properly winding thepaper on the mandrel, and between the latter and the rollers 57 and 58 Iplace a grating or guide 59 to provide a means of conducting the sheetto the chuck and to the rollers 33 and 34.

Concisely stated, the operation of the machine takes place substantiallyas follows: The web of paper is unwound from the roll and passes throughthe printing presses by which' any suitable or desirable printing,either in one or more colors, may be placed thereon. The knife 53partially or almost entirely severs the strip or web of paper intoindividual blanks or pieces,

and while still connected they pass to the feed belt 22 which conductsthe paper to the feed rollers 24 and 25. When the roller 25 descends, anaccelerated movement is given to t-he'blank between rollers 24 and.

25 which separates it from the web. The separated blank is fed forwardlyto the feeding mechanism in and above the pan 40, and at the proper timethe curling blade 27 is swung up, causing a curling of the rear portionof the blank by the drawing of the same over the edge of blade 27 as isshown in Fig. 3. In its further travel the paper blank or strip passesthrough the bath of hot melted paraflin, being coated therewith, andthen is conducted to the winding head or mandrel, the rollers 33 and 34rising automatically to receive the front end of the paper and thendescending to direct the paper beneath guide 37, which also backs awayfrom the mandrel during the insertion of the first portlon of the paper, subsequently moving up to the mandrel as will be readilyunderstood. Ordinarily about four convolutions of the paper are used foreach tube or shell, and as soon as the same has been wound on themandrel, rollers 33 and 34 and guide 37 retract, perency until the stripmitting the sliding ejector 38 to at-once distaneous shifting of thetapered bars or sections 36 It should be noticed that the portion of thepaper blank forming the inner, convolutions is not preliminarilypermanently set or curled, but that the other portion const-ituting theouter convolutions or windings is initially curled as at 51* and 51", Fig..4. The result is that in the discharged or ejected shell or tube theinner convolutions tend to expand and the outer convolutions tocontract, thereby holdingthe windings in contact during the setting orhardening of the paraflin coating, which when hot has substantially noadhesive qualities. The parafin when cold, however, acts to cement thewindings together; and the shell or tube is Water proof throughout itsentire thickness. I believe that I am the first person to provide amachine which first curlsthe strip of paper, then coats it, then windsitup into cylindrical form and then discharges it at once, depending uponthe resiliency of the paper itself to.hold it in shape during thesetting of the adhesive coating.

, The term curl as used herein means the giving of a permanent set tothe paper or tendency to curl or wind up upon itself if permitted to doso but, as will be readily understood, the feeding or conveyingmechanism in the machine prevents the paper from responding freely tothis bias or tendis wound on the mandrel or winding head.

I have not deemed it necessary or attempted to show in detail all of theminute mechanical features of the particular machine hereinabovedescribed, because they may be varied within wide limits withoutdeparture 1 from my invention, and one skilled in the art willexperience no difliculty in constructing a machine in accordance withthe principles of this invention from the disclosure herein made.
